Transaction scenarios

[Raymond Feng <en...@gmail.com>]

Hi,

I put together two scenarios on the following wiki page. We could use them 
to drive the design/implementation of the transaction policy support.

http://cwiki.apache.org/confluence/display/TUSCANYWIKI/Transaction+Intents+and+Policies

Case 1 is a money transfer action between two resource managers under the 
same global transaction. The 3 components are wired together locally using 
binding.sca.

Case 2 is an extended version where CheckingAccountService component is from 
another composite. The TransferService component talks to the 
CheckingAccountService over binding.ws. It will involve the 
WS-AtomicTransaction and the server side should be able to import the 
transaction and function as a XATerminator.

The short-term goal is to get Case 1 working. An itest has been checked in 
at 
https://svn.apache.org/repos/asf/incubator/tuscany/java/sca/itest/transaction. 
Please chime in if you are interested.

Thanks,
Raymond
